Thuasne Dynastab Dual Ankle is an ankle brace whose rigid lateral reinforcements ensure that the ankle is stable. The purpose of this garment is to immobilize the ankle and improve its mobility. The ankle braces are manufactured with nylon fabrics and can be adjusted with Velcro to fit the foot, in some cases incorporating flat metal plates to immobilize the joint. On the other hand, its use is recommended after orthopedic or surgical treatments, for ankle trauma that does not involve fractures, sprains or inflammation of the lateral ligaments, tendinitis, among other uses. To determine the use of ankle braces, the degree of the sprain, the risk factors of the affected person and the stage of recovery in which the person is in are taken into account.
